If Hetacomb is 64 squares, its two piece types make PTD of 2/64, so low that it tolerates a very high Power Density, other things equal. While true that PD is useless alone, as evaluative systems develop (necessary for sheer number of alternatives), PD stands as important measure subsuming extensive ideas of Ralph Betza and others on piece values (mobility, forwardness).
